JOSEPH GRICE, or SUTTON-COLDFIELD, ENGLAND.

COlN-OPERATED VENDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 655,437, dated August7, 1900.

Application filed February 24:, 1900. Serial No. 6,331. (No model.)

To all whom, it may concern.-

Be it known that I, JOSEPH Green, a subject of the Queen ofGreatBrit-ain and Ireland, and a resident of 38 Parade,Sutton-Coldfield, in the county of \Varwick, England, have inventedcertain new and useful Improvements Relating to Coin Operated VendingMachines, (for which I have filed an application in Great-Britain, No.15,806, hearing date August 2, 1899,) of which the following is aspecification.

This invention consists of improvements relating to coin-operatedvending-machines, my object being to prevent the freeing of theretaining mechanism by iron or steel disks or blanks and the blocking ofthe machine by such and other disks or blanks or by distorted coins orcoins of light weight or of another value than that for which themechanism is adjusted.

My invention comprises the arrangement, in combination with thecoin-admission slot and channel or chute and the coin-weighing device,of a magnet or magnets for arresting iron and steel blanks and disks andof simple and convenient means for effecting the return through the slotor admission-aperture of the machine of anything inserted therein thatwill not free the retaining mechanism or a coin of the wrong value thatmay have been inserted in error.

Referring to the three accompanying sheets of explanatory drawings,Figure 1 is a front elevation, with part in section, representing theapplication of my invention to a vending-machine of the ordinarysliding-drawer type. Fig. 2 is a sectional side elevation through theline a b, Fig. 1; and Fig. 3, a sectional plan through the line a d,Fig. 1.

The same reference-letters in the different views indicate the sameparts.

A is the drawer or pull-piece, which slides in the frame B, arranged inthe ordinary manner within or upon the outer casing of the machine, ofwhich 0 is a portion. Upon the underframe A, forming a part of andmoving with the drawer or pull-piece A, is mounted the pintle D, havingaffixed to its center the arm or lever E and to'one end of the doublepawl F, engaging with the racks G G, as shown, one of such rackspreventing the forward motion of the drawer or pull-piece A, (until thepawl is raised,) while the other prevents the return of the saidpull-piece before its forward movement is completed.

On the insertion of the proper coin through the slot oradmission-aperture at Z) it falls through the channel or chute formed bythe slotted bars H H (secured to the under side of the frame B) until itis brought to rest upon the parts 010. of the underframe A. In such aposition the coin forms an abutment for the arm or lever E, so that whenthe drawer A is pulled after the insertion of the coin the abutment ofthe said lever against the coin causes a sufficient rotation of thepintle D (against the tension of the spring J, connected with one end ofit) to lift the pawl F clear of the lower rack G, and so permit of thecomplete forward movement of the drawer.

The aforesaid mechanism constitutes no part of my invention and isreferred to only that such invention, which is hereinafter described,may be the more readily understood.

On the inner side of the frame B and be tween the slotted bars H H,forming the coin channel or chute, I mount one or more magnets K, thepoles of which are placed adja-' cent to the said coin channel or chute,so that if an iron or magnetic blank or disk be inserted through theslot I) such blank or disk is held or retained by the magnet andprevented from falling in front of the arm or lever E, hereinbeforereferred to. The magnet is omitted in Fig. 3 in order that the partsbeneath it may be clearly shown.

Beneath the magnet I arrange the coinweighing device, consisting of aproperly weighted lever L, mounted upon a projection M from theunderframe A. A portion of such lever projects at right angles to itsmain part across the front of the coin channel or chute, and pegs, as LL from such portion project across the channel or chute, as shown. Asthe proper coin descends through the chute it will on coming intocontact with the pegs L L overbalauce the lever L, and thus fall to itsposition in front of the arm or lever E; but should a light blank ordisk or a coin of light weight be used the arm or lever will not beoverbalanced, and thus the blank will be retained in the slot above thearm or lever.

For effecting the return through the slot of an iron or magnetic blankor disk or of a light coin or other article retained in the coin channelor chute and which if not removed therefrom would block the working ofthe machine I provide a returning device, as hereinafter described.

Upon a suitable part of the external casing 0, I pivot a lever N, havingits outer end formed as a handle and its inner end connected to apush-piece 0, arranged to slide vertically in guides P on the operationof the lever N, the movement of the said lever imparting the requiredreciprocating motion to the push-piece. The upper end of the pushpiece 0is preferably made of a forked shape, and when the complete push-pieceis raised by the depression of the handle end of the lever N the forksof 0 will pass between the aforesaid pegs L L on ascending through thecoin channel or chute. The push-piece is made to ascend to the top ornearly to the top of the coin channel or chute in order that it shallpush out through the slot the blank or other obstruction.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A blank-returning device for coin-operated vending-machinescomprising a chute extending from the inlet into the machine, and apush-piece with means for operating the same along the chute in'adirection opposite to the entering movement of the coin so that thespurious coins may be ejected through the inlet-opening, substantiallyas described.

2. A returning device for coin-operated vending-machines consisting of apush-piece which is free to slide within the coinchute and apush-piece-operating lever having its handle end projecting beyond theexterior of the casing of the machine, substantially as described.

3. In coin-operated vending-machines, the combination with the slottedbars H H forming the coin chute and the balance-lever L mounted on theunderframeA' of the sliding drawer A, of a push-piece 0, guides P, andpush-piece-operating lever N, substantially as set forth.

4. In coin-operated vending-machines, the combination with the slottedbars H H forming the coin-chute and the magnets K secured to the underside of the fixed frame B, of a push-piece 0, guides P, andpush-pieceoperating lever N, substantially as set forth.

In witness whereof I have hereunto set my hand in presence of twoWitnesses.
